In the field of the allocating of communication addresses to devices connected to a carrier-current communication network and more particularly, networks for the remote reading of electrical meters from a data concentration apparatus through the electrical network, there is proposed an improved method of allocating MAC addresses for this type of network making it possible to save a great deal of time during the address allocation phase. This method proposes in particular that a list associating the serial numbers of the devices and the MAC address allocated be stored at the level of the central device for allocating addresses. It is also proposed that a cataloguing request be sent, serving to allocate the MAC address prior to the sending of a communication frame.
The invention relates to a method for remotely reading consumption data on electric meters in a system comprising isolated electric meters (12, 13, 14) and a consumption data processing server (8). Each isolated electric meter (12, 13, 14) is provided with a communication means (16, 18, 21) for transmitting the consumption data specific thereto via a landline or mobile telephone communication network (9). Consumption data for a plurality of isolated meters (12, 13, 14) is first transmitted via the landline or mobile telephone communication network (9) to a unit ensuring the collection and temporary storage of consumption data for a plurality of isolated meters (12, 13, 14), and the consumption data temporarily stored by said unit (23) is then jointly addressed to the server (8). The invention applies to power dispensing networks.
